Upon lie tops of suicl scandarcls are alined horizontal bearings adapted to receive a rotary slia'e 14C, on Whose (meer enel is secured a fly-Wheel i3, provifle with a crank handle. @n the opposite end of said shaft la is secured a crank-arm lo, Whose cuter extremity is transversely oriiice to receive movabljf 'the stein of 'the *fork 71 lie stem 8 of an# other forl 4 is swiveled between the members of lie fork 7 on a pintle 6. A sleeve 18 is secured adjustalily upon said plunger-rod l by means of :1 seis-screw 3, secured so its upper pari; 2l This sleeve has integral vertically spaced horizontal flanges on opposite sides thereof, as is particularly indicated in Figs. el 06 inclusive. The upper surface of the lower flange of said sleeve has small cylindrical sockets near its ends alinecl vertically with cyclindrical orifices above in the upper flange, said orifices and sockets being adapted "so receive rotatably the antiriccon rollers l?, lie rollers being introduced from above so as 4to be easily withdrawn, if, desired. The members of the fori; 4l are slilably scemi horizontally upon and embrace? saifl oppositely placed ant-'b i'rioion rolls l? so as to contact slicla'loly therewith. l

The operation of sai actuating-means is as follovvs:"ifioen rotation is imparted to' crank to which it is connected is rotating.

tween said parts, which renders the laction very easy. 'Since the anti-friction rolls 17 are used in equally spaced pairs on opposite sides of the shaft 1, the members of the fork 4 hold them and said sleeve 18 securely while moving lthereover slidably, so that there is no danger of displacement of the fork relative to the shaft 1. Since both the pedal 6 in connecting the stein 8 to the fork 6, and the pedal of the fork 7, in its connection to the crank 16 have independent rotary actions, those parts, as Well as the anti-friction bearings above described have but little frictional wear, contributing to the ease of the operation of the device.

While have shown the members of the fork 4 as specifically seated upon anti-friction rollers 17, it is obvious that such rollers may be omitted, if desired, for the purpose of simplicity, and the fork members allowed to slidably engage opposite sides of squared seats on the shaft 1. The action would be the same in both cases, but the former device would be easier to operate. Other or di'erent forms of this device will still come within the scope and principle of my invention, where substantially the saine clonstruction is used.

Having described my invention, what claim as new, and desire to secure by Letters Patent, is

1. In combination, a plunger-rod mounted suitably for translatory and rockingv said antirictionrneansand rotary means so moyably connected to said forli as to cause the latter to impart simultaneous rocking v and translatory movements to said plunger-rod. f l

2. ln combination, a plunger-rod mounted suitably for translatory and rocking movements, a body inouiited on said rod and having spaced horizontal llanges nearl each end thereof, antifriction rollers 'seated rotatably between said flanges, a forli whose members embrace said rollers between said flanges slidably, the anges preventing disof July, i913.
